Difference between soft water blowing and steam blowing
Thread Content
Who knows the difference between soft water cleaning and steam cleaning? I want to know when to use soft water for cleaning blockages and when to use steam, so as to gain some knowledge for future pipe installation. The pipeline contains primarily sodium nitrite, sodium nitrate, and sodium carbonate, with a specific gravity of 1. 2~1. 4. The pipes get clogged very easily. I’ve been in the workshop at our factory for half a year now; I’m pretty familiar with everything else. However, there are many pipes that require soft water or steam for cleaning, and they’re all similar to each other. These methods are used infrequently, and they aren’t closely related to the production process. When it’s time to use them, it’s unclear whether soft water or steam is needed. Often, one has to trace the pipes to find the main pipe in order to know what it is! Wish everyone a happy New Year
There are generally two situations regarding purging: 1. A certain medium is introduced to carry out continuous purging in order to keep the pipeline unobstructed, such as in the pipeline behind a safety valve； 2. It is not used under normal circumstances; it is only employed for clearing blockages in the pipes when such blockages are detected. For the former case, I personally think steam is better, as in addition to cleaning, it can also raise the temperature of the pipes, making it easier to check whether they are unobstructed ； In the latter case, both methods should be used: when a blockage is detected, first dissolve the crystals with deionized water, and then purge and preheat the pipelines with steam. Of course, it’s best to have high-temperature steam condensate.
I’ll add another example: when I was on site, there was a level gauge that needed to be cleaned regularly. Initially, steam was planned to be used for this purpose, but the instrumentation team on site disagreed, as the designed operating temperature of that level gauge was low, and steam would damage it. Later, hot water was used instead. In terms of the effectiveness of purging, steam is the best option, but it’s necessary to consider specific circumstances such as whether the material is heat-sensitive and the designed operating temperature of the equipment; in short, flexibility is key

Is there a difference from purging? Generally, liquid pipelines with a nominal diameter of less than 600 are purged with water; soft water can be used for applications requiring higher standards. Gas pipelines with a nominal diameter of less than 600 are purged with air. Steam pipes are purged with steam. Non-thermal pipelines must not be cleaned using steam pipelines.
